AI Article Synopsis

  • Numerous treatments for critical limb ischemia (CLI) have struggled in clinical trials, especially stem cell therapy, which generally sees low patient survival rates.
  • This study explored how polydeoxyribonucleotide (PDRN) affects stem cells from human deciduous teeth (SHED), finding that PDRN boosts their growth, movement, antioxidant abilities, and energy production through Akt activation.
  • PDRN-enhanced SHED not only survived better in an ischemic environment but also showed potential as a new therapeutic option for CLI, highlighting the importance of Akt in this process.

Article Abstract

Although numerous approaches have emerged to address the challenges of critical limb ischemia (CLI), their clinical trials have proven elusive. Stem cell therapy has been utilized for CLI; however, its efficacy is limited, resulting in low survival rates in patients. Here, we investigated the impact of polydeoxyribonucleotide (PDRN) on the bioactivities of stem cells derived from human exfoliated deciduous teeth (SHED) against oxidative stress. PDRN treatment increased the proliferation, migration, antioxidant properties, and mitochondrial respiration of SHED. These beneficial effects were regulated by Akt activation. Through a murine hindlimb ischemia model, PDRN treatment demonstrated augmented the survival and proliferation of transplanted SHED at ischemic injury sites, whereas the inhibition of Akt suppressed these effects. Our findings revealed that PDRN promoted the therapeutic potential of SHED via Akt phosphorylation, suggesting PDRN-primed SHED as promising candidates for the development of novel stem cell therapeutics.

Over the past decade, research on embryo-derived extracellular vesicles (EVs) has unveiled their critical roles in embryonic development and intercellular communication. EVs secreted by embryos are nanoscale lipid bilayer vesicles that carry bioactive cargo, including proteins, lipids, RNAs, and DNAs, reflecting the physiological state of the source cells. These vesicles facilitate paracrine and autocrine signaling, influencing key processes such as cell differentiation, embryo viability, and endometrial receptivity.

Mesenchymal Stem Cell-Sourced Exosomes as Potentially Novel Remedies for Severe Dry Eye Disease.

Severe dry eye disease (DED) is an inflammatory condition characterized by a lack of sufficient moisture or lubrication on the surface of the eye, significantly impacting the quality of life and visual function. Since detrimental immune response is crucially responsible for the development and aggravation of DED, therapeutic agents which modulate phenotype and function of eye-infiltrated inflammatory immune cells could be used for the treatment of severe DED. Due to their potent immunomodulatory properties, mesenchymal stem cells (MSCs) represent potentially new remedies for the treatment of inflammatory eye diseases.

Background: Given the risks associated with autologous bone transplantation and the limitations of allogeneic bone transplantation, scaffolds in bone tissue engineering that incorporate bioactive peptides are highly recommended. Teriparatide (TPTD) plays a significant role in bone defect repair, although achieving controlled release of TPTD within a bone tissue engineering scaffold remains challenging. This work reports a new approach for treatment of teriparatide using a water-in-oil-in-water (w/o/w) microspheres be equipped on gelatin (GEL)/Poly lactic-glycolic acid (PLGA)/attapulgite (ATP) scaffold.

Exosomes, the bioactive particles secreted by various cells, are essential in mediating cellular communication. However, their small size and the interference from non-exosome proteins present significant hurdles for their rapid and non-destructive capture and release. To overcome these obstacles, a promising strategy to efficiently and selectively isolate exosomes from mesenchymal stem cells (MSCs) is developed by using CD63 aptamer-conjugated magnetic nanoparticles (FeO-Aptamer).

Denervated muscle atrophy, a common outcome of nerve injury, often results in irreversible fibrosis due to the limited effectiveness of current therapeutic interventions. While extracellular vesicles (EVs) offer promise for treating muscle atrophy, their therapeutic potential is hindered by challenges in delivery and bioactivity within the complex microenvironment of the injury site. To address this issue, an injectable hydrogel is developed that is responsive to both ultrasound and pH, with inherent anti-inflammatory and antioxidant properties, designed to improve the targeted delivery of stem cell-derived EVs.
